Federico Faggin (Italian pronunciation: [fedeˈriːko fadˈdʒin], Venetian: [faˈdʒiŋ]; born 1 December 1941) is an Italian-American physicist, engineer, inventor and entrepreneur. He is best known for designing the first commercial microprocessor, the Intel 4004. He led the 4004 (MCS-4) project and the design group during the first five years of Intel's microprocessor effort. Faggin also created, while working at Fairchild Semiconductor in 1968, the self-aligned MOS (metal–oxide–semiconductor) silicon-gate technology (SGT), which made possible MOS semiconductor memory chips, CCD image sensors, and the microprocessor. After the 4004, he led development of the Intel 8008 and 8080, using his SGT methodology for random logic chip design, which was essential to the creation of early Intel microprocessors. He was co-founder (with Ralph Ungermann) and CEO of Zilog, the first company solely dedicated to microprocessors, and led the development of the Zilog Z80 and Z8 processors. He was later the co-founder and CEO of Cygnet Technologies, and then Synaptics.

In 2010, he received the 2009 National Medal of Technology and Innovation, the highest honor the United States confers for achievements related to technological progress. In 2011, Faggin founded the Federico and Elvia Faggin Foundation to support the scientific study of consciousness at US universities and research institutes. In 2015, the Faggin Foundation helped to establish a $1 million endowment for the Faggin Family Presidential Chair in the Physics of Information at UC Santa Cruz to promote the study of "fundamental questions at the interface of physics and related fields including mathematics, complex systems, biophysics, and cognitive science, with the unifying theme of information in physics."

Education and early career

Born in Vicenza, Italy, Federico grew up in an intellectual environment. His father, Giuseppe Faggin, was a scholar who wrote many academic books and translated, with commentaries, the Enneads of Plotinus from the original Greek into modern Italian. Federico had a strong interest in technology from an early age. He attended a technical high school in Vicenza, I.T.I.S. Alessandro Rossi, and later earned a laurea degree in physics, summa cum laude, from the University of Padua.

Olivetti R&D Labs

Faggin joined Olivetti aged 19. There he co-designed and led the implementation of a small digital transistor computer with 4 K × 12 bit of magnetic memory (1960). The Olivetti R&D department subsequently developed one of the world's first programmable desktop electronic calculators, the Olivetti Programma 101 (1964). After this first work experience, Faggin studied physics at the University of Padua and taught the electronics laboratory course for 3rd year physics students in the academic year 1965–1966.

SGS-Fairchild

In 1967, he joined SGS-Fairchild, in Italy, where he developed its first MOS metal-gate process technology and designed its first two commercial MOS integrated circuits. SGS sent him to California in 1968. When Fairchild sold SGS-Fairchild, Faggin accepted an offer to complete the development of the silicon-gate technology with Fairchild.

Silicon Valley career

Fairchild Semiconductor

The silicon-gate technology (SGT) is one of the most influential technologies to have fueled the progress of microelectronics since the MOSFET. Without the SGT, the first microprocessor could not have been made during 1970–1971.

In February 1968, Federico Faggin joined Fairchild Semiconductor in Palo Alto where he was the project leader of the MOS silicon-gate technology, a MOSFET with a silicon self-aligned gate, and the inventor of its unique process architecture. The SGT became the basis of all modern NMOS and CMOS integrated circuits. It made possible the creation of MOS semiconductor memory chips during 1969–1970, the first microprocessor during 1970–1971, and the first CCD and EPROM (electrically programmable read-only memory) with floating silicon gates (1970–1971). The SGT replaced the incumbent aluminum-gate MOS technology, and was adopted worldwide within 10 years, eventually making obsolete the original integrated circuits built with bipolar transistors.

Fairchild 3708

At Fairchild, Faggin designed the first commercial integrated circuit using silicon-gate technology with self-aligned MOSFET transistors: the Fairchild 3708. The 3708 was an 8-bit analog multiplexer with decoding logic, replacing the equivalent Fairchild 3705 that used metal-gate technology. The 3708 was 5 times faster, had 100 times less junction leakage and was much more reliable than the 3705, demonstrating the superiority of SGT over metal-gate MOS. See also: Faggin, F., Klein T. (1969). "A Faster Generation of MOS Devices With Low Threshold Is Riding The Crest of the New Wave, Silicon-Gate IC's". Electronics, 29 Sep. 1969.

Intel

Federico Faggin joined Intel from Fairchild in 1970 as the project leader and designer of the MCS-4 family of microprocessors, which included the 4004, the world's first single-chip microprocessor. Fairchild was not taking advantage of the SGT and Faggin wanted to use his new technology to design advanced chips.

The 4004 (1971) was made possible by the advanced capabilities of the silicon gate technology (SGT) being enhanced through the novel random logic chip design methodology that Faggin created at Intel. It was this new methodology, together with his several design innovations, that allowed him to fit the microprocessor in one small chip. A single-chip microprocessor – an idea that was expected to occur many years in the future – became possible in 1971 by using SGT with two additional innovations: (1) "buried contacts" that doubled the circuit density, and (2) the use of bootstrap loads with 2-phase clocks—previously considered impossible with SGT— that improved the speed 5 times, while reducing the chip area by half compared with metal-gate MOS.

The design methodology created by Faggin was utilized for the implementation of all Intel's early microprocessors and later also for Zilog's Z80.

The Intel 4004 – a 4-bit CPU (central processing unit) on a single chip – was a member of a family of 4 custom chips designed for Busicom, a Japanese calculator manufacturer. The other members of the family (constituting the MCS-4 family) were: the 4001, a 2k-bit metal-mask programmable ROM with programmable input-output lines; the 4002, a 320-bit dynamic RAM with a 4-bit output port; and the 4003, a 10-bit serial input and serial/parallel output, static shift register to use as an I/O expander. Faggin promoted the idea of broadly marketing the MCS-4 to customers other than Busicom by showing Intel management how customers could design a control system using the 4004. He designed and built a 4004 tester using the 4004 as the controller of the tester, thus convincing Bob Noyce to renegotiate the exclusivity clause with Busicom that didn't allow Intel to sell the MCS-4 line to other customers.

In 2009, the four contributors to the 4004 were inducted as Fellows of the Computer History Museum. Ted Hoff, head of Application Research Department, formulated the architectural proposal and the instruction set with assistance from Stan Mazor and working in conjunction with Busicom's Masatoshi Shima. However, none of them was a chip designer and none was familiar with the new Silicon Gate Technology (SGT). The silicon design was the essential missing ingredient to making a microprocessor since everything else was already known. Federico Faggin led the project in a different department without Hoff's and Mazor's involvement. Faggin had invented the original SGT at Fairchild Semiconductor in 1968 and provided additional refinements and inventions to make possible the implementation of the 4004 in a single chip. With routine help from Shima, Faggin completed the chip design in January 1971.

The Intel 2102A is a redesign of the Intel 2102 static RAM, where Federico Faggin introduced to Intel, for the first time, the depletion load, combining the silicon gate technology with ionic implantation. The design was done toward the end of 1973 by Federico Faggin and Dick Pashley. The 2102A was 5 times faster than the 2102, opening a new direction for Intel.

Early Intel microprocessors

Faggin's silicon design methodology was used for implementing all Intel's early microprocessors.

The Intel 8008 was the world's first single-chip 8-bit CPU and, like the 4004, was built with p-channel SGT. The 8008 development was originally assigned to Hal Feeney in March 1970 but was suspended until the 4004 was completed. It was resumed in January 1971 under Faggin's direction utilizing the basic circuits and methodology he had developed for the 4004, with Hal Feeney doing the chip design. The CPU architecture of the 8008 was originally created by CTC Inc. for the Datapoint 2200 intelligent terminal, in which it was implemented in discrete IC logic.

The Intel 4040 microprocessor (1974) was a much improved, machine-code-compatible version of the 4004 CPU allowing it to interface directly with standard memories and I/O devices. Federico Faggin created the architecture of the 4040 and supervised Tom Innes who did the design work.

The 8080 microprocessor (1974) was the first high-performance 8-bit microprocessor in the market, using the faster n-channel SGT. The 8080 was conceived and architected by Faggin, and designed by Masatoshi Shima under Faggin's supervision. The 8080 was a major improvement over the 8008 architecture, yet it retained software compatibility with it. It was much faster and easier to interface to external memory and I/O devices than the 8008. The high performance and low cost of the 8080 let developers use microprocessors for many new applications, including the forerunners of the personal computer.

When Faggin left Intel at the end of 1974 to found Zilog with Ralph Ungermann, he was R&D department manager responsible for all MOS products, except for dynamic memories.

Zilog

The Zilog Z80 was the first microprocessor created by Zilog, the first company entirely dedicated to microprocessors. It was started by Federico Faggin and Ralph Ungermann in November 1974. Faggin was Zilog's president and CEO until the end of 1980 and he conceived and designed the Z80 CPU and its family of programmable peripheral components. He also co-designed the CPU whose project leader was Masatoshi Shima. The Z80-CPU was a major improvement over the 8080, yet it retained software compatibility with it. Much faster and with more than twice as many registers and instructions of the 8080, it was part of a family of components that included several intelligent peripherals (the Z80-PIO, a programmable parallel input-output controller; the Z80-CTC, a programmable counter-timer; the Z80-SIO, programmable serial communications interface controller, and the Z80-DMA, programmable direct memory access controller). This chip family allowed the design of powerful and low-cost microcomputers with performance comparable to minicomputers. The Z80-CPU had a substantially better bus structure and interrupt structure than the 8080 and could interface directly with dynamic RAM, since it included an internal memory-refresh controller. The Z80 was used in many of early personal computers, as well as in video game systems such as the MSX, ColecoVision, Master System and Game Boy. The Z80 ceased production in 2024.

The Zilog Z8 micro controller (1978) was one of the first single-chip microcontrollers in the market. It integrated an 8-bit CPU, RAM, ROM and I/O facilities, sufficient for many control applications. Faggin conceived the Z8 in 1974, soon after he founded Zilog, but then decided to give priority to the Z80. The Z8 was designed in 1976–78 and ended production in 2024.

The Communication CoSystem

The Communication CoSystem (1984). The Cosystem was conceived by Faggin and designed and produced by Cygnet Technologies, Inc., the second startup company of Faggin. Attached to a personal computer and to a standard phone line, the CoSystem could automatically handle all the personal voice and data communications of the user, including electronic mail, database access, computer screen transfers during a voice communication, call record keeping, etc. The patent covering the CoSystem is highly cited in the personal communication field.

Synaptics

In 1986 Faggin co-founded and was CEO of Synaptics until 1999, becoming chairman from 1999 to 2009. Synaptics was initially dedicated to R&D in artificial neural networks for pattern-recognition applications using analog VLSI. Synaptics introduced the I1000, the world's first single-chip optical character recognizer in 1991. In 1994, Synaptics introduced the touchpad to replace the cumbersome trackball then in use in laptop computers. The touchpad was broadly adopted by the industry. Synaptics also introduced the early touchscreens that were eventually adopted for intelligent phones and tablets; applications that now dominate the market. Faggin came up with the general product idea and led a group of engineers who further refined the idea through many brainstorming sessions. Faggin is a co-inventor of ten patents assigned to Synaptics. He is chairman emeritus of Synaptics.

Foveon

During his tenure as president and CEO of Foveon, from 2003 to 2008, Faggin revitalized the company and provided a new technological and business direction resulting in image sensors superior in all critical parameters to the best sensors of the competition, while using approximately half the chip size of competing devices. Faggin also oversaw the successful acquisition of Foveon by the Japanese Sigma Corporation in November 2008.

Federico and Elvia Faggin Foundation

Founded in 2011 the "Federico and Elvia Faggin Foundation" supports the scientific study of consciousness at US universities and research institutes. The purpose of the Foundation is to advance the understanding of consciousness through theoretical and experimental research. Faggin's interest in consciousness has his roots in the study of artificial neural networks at Synaptics, a company he started in 1986, that prompted his inquiry into whether or not it is possible to build a conscious computer.

The theory of consciousness

In a book in Italian: "Irriducibile. La coscienza, la vita, i computer e la nostra natura" (Mondadori, 2022) Federico Faggin proposed a theory of consciousness according to which consciousness is a purely quantum phenomenon, unique to each of us. This theory is supported by two quantum physics theorems: the no-cloning theorem and Holevo's theorem. The first states that a pure quantum state is not reproducible; the second limits the amount of measurable information to one classical bit for each qubit that describes the state. Therefore, it is possible to postulate that a quantum system that is in a pure state is aware of its state, since conscious experiences (qualia) have all the essential properties of pure states, i.e., it is private knowledge only minimally knowable from the outside. However, the mathematical representation of the experience (the pure state) does not describe the experience, which remains private and knowable only from within by the system that is in that state. No classical machine can ever be conscious given that classical information is reproducible (program and data can be copied perfectly), while the quantum state is private. Consciousness is therefore not linked to the functioning of the body and can continue to exist even after the death of the body. The body behaves like a drone controlled "top down" by consciousness. The new D'Ariano-Faggin theory is based on the theoretical studies of Professor Giacomo D'Ariano's studies, who derived quantum theory from informational principles , and on the experiential, philosophical and scientific studies of Federico Faggin on the nature of consciousness.
